Wikimedia Commons/One Night Only movie Movie One Night Only flips The Purge premise into a rom-com: premarital sex is banned except for one wild, legal night a year. April 29, 2026 AceShowbiz - One Night Only is a new film with a premise that echoes dystopian themes, but this time it pivots from horror to romantic comedy. The original The Purge series, starting in 2013, centers around an America plagued by crime and overcrowded prisons, where the government allows a 12-hour window annually for all criminal acts to be legal. However, this new film takes a markedly different approach.
